3 Claims.

This invention relates to a detachable shoe sole structure. r

In the playing of athletic games or the like wherein the use ofanti-slipping devices associated with the footwear is necessary,considerable inconvenience has been experienced in that the customarypractice has been to provide an additional pair of shoes having cleatsor the like, to be used during participation in the athletic game. Ingolf playing, for instance, the player cannot in the nature of thingswear the playing shoes to and from the course or in case an automobileis used, the cleats or spikes of the conventional sport shoe render themanipulation of the control pedals quite difficult. The presentinvention comprehends the use of a detachable shoe sole structure whichprovides all of the attributes of an athletic shoe or the like and whichobviates the above and other difficulties experienced by those wearingshoes of the nature stated. 7

' One object of the invention, therefore,'is the provision of adetachable shoe sole structure which may be effectively secured toordinary foot wear and which provides the advantages of a sport shoe orthe like, without necessitating the removal of the ordinary foot wear.

Another object of the invention is to provide a detachable shoe solestructure of this character'which is equipped with anti-slipping devicessuch as spikes, cleats, hobnails or the like, and which is adapted foruse in athletic sports, such as golf playing and the like but whichlikewise may be used by miners, lumber-jacks,

farm hands and various other laborers.

Another object of the invention is the provision of a detachable shoesole structure which may be quickly applied and removed and which isprovided with securing means adapted to fit shoes of different sizes.

A further object of the invention resides in the provision of a deviceof this character which is provided with a flexible cap portion adaptedto secure the structure to the toe portion of the shoe of the wearer andto completely cover and protect the toe of the shoe.

A still further object of the invention lies in the provision of adetachable shoe sole structure which is of light weight, simple inconstruction, durable and efficient in operation and yet comparativelyinexpensive of manufacture.

The novel features that I consider characteristic of the invention areset forth with particularity in the appended claims. The inventionitself both as to its construction and use, to-

Fig. 4 is a transverse section taken on lin 4-4 of Figure 2 and showinga preferred embodiment of the anti-slipping device.

Fig. 5 is a top plan view showing a modification of the invention,wherein a flexible cap is substituted in lieu of the flexible securingmeans shown in Figures 1 and 2. r

Fig. 6 is a transverse section taken on line 6-6 of Figure 5.

Referring to the drawing in detail, whereinis shown in Figures 1 to 4,inclusive, a preferred form of my invention, 1 designates the detachableshoe sole which is made of a suitable flexible material such as leatheror the like.

The detachable sole is adapted to be applied to ordinary footwear byflexible securing means A at the front portion thereof and rigidclamping means B at the rear portion thereof.

The flexible securing means A which serves to removably and adjustablysecure the front portion of the detachable sole to the cap portion ofthe shoe of the wearer consists of a curved rearwardly extendingflexible strap 2 and a curved flexible cross strap 3 associatedtherewith.

The outermost front edge portion of the detachable sole 1 is providedwith a substantially right angled lug 4 having an inwardly directedflange 5 secured thereto by means of a rivet 6. The projecting end 7 ofthe lug is provided with a horizontally extending strap-receivingopening. 8. One end of the flexible strap 2 is looped through theopening 8 of the lug 4 and then suitably secured as at 9 and the otherend at its rear portion is provided with longitudinally extending slitssuch as shown at 10 for the reception of the curved cross strap 3.

The front portion of the detachable sole 1 is further provided withsimilar lug members 11 and 12 having inwardly directed flange portions13 and 14, respectively, which are secured to the bottom of the sole 1in any conventional manner, as by rivets 15 and 15'. The projecting ends16 and 17 of the lugs 11 and 12, respectively, are provided withhorizontally extending strap-receiving openings as shown at 16'. Theflexible strap 3 has connection with these strap-receiving openings loo.. the adjustable clamping member 25.

and may be adjusted by means of the buckle l8 and the cooperatingapertures 3' in the free end thereof.

It will be noted that by the arrangement of the flexible strap-securingmeans as described, the forward portion of the detachable sole may beeffectively and securely held in operative position relative to the shoeof the wearer and that the securing means is readily adjustable toconform to the forward or cap portion of shoes of various sizes andcontours.

The rear portion of the detachable sole 1 is adapted to be adjustablyand removably secured to the shank of the shoe sole of the wearer bymeans of the clamping device B which comprises a stationary clampinghook, an adjustable clamping hook and means for adjusting the latter.

The stationary, rigid clamping member 19 is secured to a relativelyflexible member 20 by rivets 21 or the like, which flexible member issecured to the rear portion of the detachable sole 1, as by rivets 22,but if desired, the interposed flexible member 20 may be dispensed withand the stationary clamping member mounted directly on the rear portionof the detachable sole. The stationary clamping member 19 is provided atone side edge thereof with an integrally conneoted, upstanding clampinghook 23, the upper portion of which has an inwardly directed lip portion24. The clamping hook 23 is designed to embrace and hook over one edgeof the shank of the shoe sole on which the detachable sole is worn. Anadjustable clamping member 25 is secured to the stationary clampingmember 19 by means of a bolt 26 and nut 27. The bolt passes downwardlythrough a suitable aperture in the stationary clamping member 19 andextends through the transversely extending opening 28 in The adjustableclamping member 25 is provided on one end with upstanding clamping hook29, the upper portion of which has an inwardly directed lip portion 30.The clamping hook 29 is complemental with respect to the clamping hook23 and is designed to embrace and hook over the opposite edge of thesaid shank portion. The other end of the adjustable member 25 isprovided with a depending lug 31 forming an abutment 32.

A camming member which is shown in the form of an eccentric disk 33 isdisposed beneath the lower side of the adjustable clamping member 25 andis adjustably and pivotally secured to the stationary clamping member 19by means of the bolt 26 and nut 27. The camming member or eccentric disk33 is adapted to revolve about its pivotal point to engage the abutment32 of the adjustable clamping member 25 to impart an inward movement tothe adjustable clamping member 25, thereby bringing the clamping hook 29into clamping engagement with one edge of the shank sole.

In order to guide the adjustable clamping member 25 so as to prevent anyappreciable amount of lateral movement when the clamping hook 29 ismoved into clamping position, there is provided a bolt 34 which passesdownwardly through a suitable aperture in the stationary clamping member19 and extends through the transversely extending opening 28 in theadjustable clamping member 25 after which the nut 35 is applied. Ifdesired, the bolt may be upset so as to lock the nut on the bolt. 1

The curved camming member or eccentric 33 is provided near itsperipheral edge with a plurality of spaced openings 36 of varying size.It

will be apparent that the nut 27 of the bolt 26 may be removed and thebolt inserted in any of the various openings 36 as may be desirable inorder to regulate the length of throw of the curved camming member withrespect to its pivotal point.

After the clamping hook 29 has been brought into engagement with theshank sole of the shoe so that the shank sole is securely held betweenthe clamping hooks 23 and 29, the bolt 26 may be tightened to lock thecamrning member 33 in position to thereby hold the clamping hooks inoperative position.

In the specific embodiment of the invention as shown, the bottom of thesole 1 is provided near its side and front edges with a row ofanti-slipping devices or metallic cleats 3'7 and a third row extendinglongitudinally of the sole and being substantially equi-distant fromopposite edges of the sole. The cleats 37 are so arranged that whenviewed in either a longitudinally or transversely extending plane, theyare in staggered relationship with respect to each other. As shown,these cleats comprise an abutment 38 having a depending cylindricalportion 39 and an upwardly extending hollow shank portion 40 which ispassed through the sole from the outside of the shank and then riveteddown upon the top of the sole, as shown at 41, to securely fasten thecleats in place.

When the device is placed upon a shoe, the riveted heads 41 of the shank40 provide a frictional engagement with the shoe and serve to retardrelative movement between the same.

In Figures 5 and 6, there is shown a modification of the invention whichmay be substituted in lieu of the flexible securing means A, forsecuring the front portion of the detachable sole to the cap portion ofthe shoe of the wearer as set forth in Figures 1 to 4, inclusive, itbeing understood, of course, that the modifled'flexible securing meansis intended to be used in conjunction with the clamping structure 13, asabove described, for securing the rear portion of the detachable sole tothe shank sole of the shoe.

As shown in Figures 5 and 6, the modification comprises anarcuate-shaped lug member 42 having an inwardly directed flange 43 andan upstanding flange 44, the former of which engages the forward portionof the detachable sole 1 adjacent its edge and is secured thereto byrivets 45 or the like, and the latter of which engages the outer edge ofthe detachable sole and projects beyond the top thereof. Thearcuate-shaped lug member 42 extends from a point 46 on one side of thedetachable sole adjacent its forward end clear around the tip thereof toan opposite point 47 on the other side of the sole.

The projecting flange 44 is provided with a plurality of perforations,as shown at 48, to facilitate the securing of the lower edges 49 of thecap portion 50 to the projecting flange 44, as by sewing thereby givinga neat and finished appearance to the article.

The cap portion 50 is provided with a longitudinally extending opening,which opening is adapted to be closed by means of a separable fastenercomprising a fastener element 51 secured to one of the marginal edges ofthe opening as at 52 and a similar fastener element 53 in oppositelydisposed relationship as at 54 and a cooperating slidable closure member55 operable by the member 56, the device being commonly known as azipper.

It will be apparent that this device facilitates the ready applicationof the cap-securing means Ibo to the toe portion of the shoe of thewearer, and that the cap in addition to providing a securing means,serves further to completely cover and protect the toe of the shoeagainst hard usage.

Although I have shown and described specific embodiments of myinvention, I am fully aware that many modifications thereof arepossible. My invention,jtherefore, is not to be limited or restrictedexcept insofar as is necessitated by the scope of the appended claims.
